Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of door and window fitting production, in particular to a production mold frame of door and window composite profiles. BACKGROUND

[0002] The door and window composite profile is a material with multiple properties by combining different materials into one material. Generally, the door and window composite profile includes three layers, namely an indoor layer, an outdoor layer, and a heat insulation layer arranged between the indoor layer and the outdoor layer. The indoor layer and the outdoor layer are usually made of aluminum alloy, and the heat insulation layer is made of polyurethane foam. Taking polyurethane as an example, according to the layered structure of the door and window composite profile, an injection mold is usually used for production. The polyurethane used for producing the door and window profile is injected into the inner cavity of the mold, and the process of foaming and curing is used to connect with other profiles to form a door and window composite profile with smooth surface, exquisite external appearance, and uniform density.

[0003] The mold in the prior art is usually divided into an upper mold and a lower mold. In the production process of the composite profile, the upper mold is driven by a lifting device to realize the clamping or unclamping operation with the lower mold. However, due to the large length of the door and window composite profile, the length and weight of the corresponding upper mold increase, which leads to high energy consumption of the device driving the lifting movement of the upper mold, and the device driving the movement of the upper mold is laborious, thereby reducing the stability and safety of the device. Moreover, when the product is taken out, enough space is required between the upper mold and the lower mold to inject raw materials into the mold cavity and take out the product after molding. However, this increases the height space occupied by the entire production mold frame including the lifting device and the mold. Therefore, the mold is adjusted to be a turnover type, and the upper mold is driven to rotate relative to the lower mold by a connecting rod mechanism. Although this can reduce the space occupied by the device in the horizontal direction, if the length of the connecting rod is large, it can increase the torque and facilitate the rotation of the upper mold, but the space occupied in the horizontal direction increases. If the length of the connecting rod is too small, the torque decreases, which requires more power to drive the rotation of the upper mold, and the load of the device driving the rotation of the upper mold increases, thereby reducing the overall safety and stability of the mold frame.

[0004] Therefore, it is necessary to improve the production mold frame of the door and window composite profile in the prior art. SUMMARY

DETAILED DESCRIPTION

[0032] The specific embodiments of the application will be further described below in conjunction with the drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the application, and cannot be used to limit the protection scope of the application.

[0033] First embodiment

[0034] As shown in Figures 1-6 , the production mold frame of the door and window composite profile of the first embodiment of the application,

[0035] The mold extends along a horizontal direction and comprises a lower mold 100 and an upper mold 200 rotationally connected with the lower mold 100, the upper mold 200 has two end positions relative to the rotation path of the lower mold 100, which are a mold closing position and a mold opening position, the end of the upper mold 200 is a supported part 201 which is horizontally projected and separated from the horizontal projection of the lower mold 100, the two sides of the vertical plane where the rotation axis of the upper mold 200 is located are a mold closing side and a mold opening side respectively, the distance between the gravity center of the upper mold 200 and the rotation axis of the upper mold 200 is a first distance, the distance between the supported part 201 and the rotation axis of the upper mold 200 is a second distance, the first distance is smaller than the second distance, the upper mold 200 and the lower mold 100 enclose a mold cavity at the mold closing position, and the gravity center of the upper mold 200 and the supported part 201 are located at the mold closing side, the gravity center of the upper mold 200 and the supported part 201 are located at the mold opening side at the mold opening position.

[0036] The driving assembly comprises a lifting device 300 and a support guide 400 connected with the output end of the lifting device 300, the support guide 400 has two support guide parts 401 for supporting the supported part 201.

[0037] When the lifting device 300 drives the support guide 400 to move up and down and is connected with the supported part 201 to support the rotation of the upper mold 200, the two support guide parts 401 are separately arranged at the mold closing side and the mold opening side and the length direction is perpendicular to the rotation axis of the upper mold 200, the horizontal distance between the supported part 201 and the rotation axis of the upper mold 200 is negatively related to the lifting height of the support guide 400, the supported part 201 is driven by the upper mold 200 to move from the mold opening side support guide part to the mold closing side support guide part when the gravity center of the upper mold 200 moves from the mold opening side to the mold closing side, and the supported part 201 is driven by the upper mold 200 to move from the mold closing side support guide part to the mold opening side support guide part when the gravity center of the upper mold 200 moves from the mold closing side to the mold opening side.

[0038] Specifically, in the present application, the lower mold 100 and the upper mold 200 are both long strips and extend along a horizontal direction, the bottom of the lower mold 100 is provided with a plurality of support columns 800 which are distributed at intervals along the length direction of the lower mold 100, the bottom end of the support column 800 is fixed on the bottom surface to horizontally support the lower mold 100, one side of the top of the lower mold 100 is connected with the upper mold 200 through a hinge 700, and the rotation axis of the upper mold 200 is parallel to the length direction of the upper mold 200.

[0039] When the upper mold 200 rotates to the mold closing position, as shown in Figure 5 (a), the upper mold 200 covers the mold cavity opening of the lower mold 100, and when the upper mold 200 rotates to the mold opening position, as shown in Figure 5 (d), the side of the upper mold 200 for covering the mold cavity opening of the lower mold 100 faces upward, that is, the upper mold 200 rotates by 180° between the mold opening position and the mold closing position.

[0040] As shown in Figure 3As shown, the dashed line intersects the rotation axis of the upper die 200, and together they determine the vertical plane in which the rotation axis of the upper die 200 is located, that is, the rotation axis of the upper die 200 and the dashed line are both located on the vertical plane, and correspondingly, the left side of the dashed line, that is, the A side is the parting side, and the right side of the dashed line, that is, the B side is the clamping side.

[0041] The end of the upper die 200 is provided with a receiving portion 201, and the vertical projection of the receiving portion 201 on the horizontal plane is separated from the vertical projection of the lower die 100 on the horizontal plane. The lifting device 300 is a lifting cylinder, the cylinder barrel of which is fixed to the bottom surface and is arranged upward, the top of the piston rod is connected with the support guide 400, the support guide 400 is located directly below the receiving portion 201 and is separated from the lower die 100, the support guide 400 is a vertical plate structure, and two support guide portions 401 are formed on the top surface of the support guide 400. When the lifting device 300 operates, the support guide 400 acts on the receiving portion 201, specifically, one of the support guide portions 401 acts on the receiving portion 201, drives the receiving portion 201 to move up and down, and further drives the upper die 200 to rotate. During the rotation of the upper die 200, the movement direction of the receiving portion 201 is divided into two directions, one is the vertical direction, and the other is the horizontal direction. With the rotation of the upper die 200, the receiving portion 201 moves in the horizontal direction, and then the receiving portion 201 moves from one support guide portion 401 to the other support guide portion 401. At this time, the center of gravity of the upper die 200 moves from one side of the vertical plane in which the rotation axis of the upper die 200 is located to the other side, thereby completing the rotation of the upper die 200 and realizing the parting and clamping operations of the upper die 200 and the lower die 100.

[0042] Compared with the production mold frame in the prior art, the height space occupied by the mold frame is greatly reduced, the support guide 400 is driven by the lifting device 300 to move up and down and acts on the receiving portion 201, and then drives the upper die 200 to rotate. The second distance is greater than the first distance, so that the torque for driving the upper die 200 to rotate is increased, thereby reducing the driving force for driving the upper die 200 to rotate, that is, reducing the maximum load requirement of the lifting device 300, so that the mold frame operates more completely and stably.

[0043] Further improvement is that the driving assembly is provided with two, which are located at both ends of the mold, and the two ends of the upper die 200 are provided with the receiving portion 201 and correspond to the driving assembly one by one. After adopting this structure, when the upper die 200 is driven to rotate, the lifting devices 300 at both ends act at the same time, so that the upper die 200 rotates more stably. Furthermore, when the two lifting devices 300 act together, compared with a single lifting device 300, they can jointly bear the gravity of the upper die 200, further reducing the load requirement of the lifting device 300.

[0044] Further improvement is that the trusted part 201 is a trusted roller rotating around its axis, and the axis of the trusted roller is parallel to the rotating axis of the upper die 200. After the trusted part 201 is set on the trusted roller, when the upper die 200 is driven to rotate, the trusted roller abuts against the support guide part 401 of the support guide 400 and rolls on the support guide part 401, which reduces the abrasion between the trusted part 201 and the support guide 400 and makes the rotation of the upper die 200 more stable and energy-saving.

[0045] Further improvement is that the center of gravity of the upper die 200 is located above the side of the clamping side support guide part when the center of gravity of the upper die 200 is transferred from the parting side to the clamping side, and the center of gravity of the upper die 200 is located above the side of the parting side support guide part when the center of gravity of the upper die 200 is transferred from the clamping side to the parting side.

[0046] After the above structure is adopted, when the center of gravity of the upper die 200 is located on the parting side or the clamping side, the relative height positions of the two support guide parts 401 of the support guide 400 for driving the rotation of the upper die 200 are adjusted, so that when the lifting device 300 drives the support guide 400 to move up and down, the trusted part 201 rolls from the relatively higher support guide part 401 to the relatively lower support guide part 401 and will not move to the support guide part 401 with a relatively higher position, which avoids the return of the trusted part 201 to the original position and the rotation of the upper die 200, thereby ensuring the rotation of the upper die 200 in a fixed direction.

[0047] Further improvement is that the two support guide parts 401 are connected by a circular arc. After the above structure is adopted, the trusted part 201 can move smoothly from the support guide part 401 with a relatively higher position to the support guide part 401 with a relatively lower position, which avoids the vibration of the trusted part 201 and ensures the smooth rotation of the upper die 200.

[0048] Further improvement is that the two ends of the two support guide parts 401 are valley ends 4011 and peak ends 4012, the valley end 4011 is arranged between the peak end 4012 and the rotating axis of the upper die 200, and the peak end 4012 is higher than the valley end 4011 and gradually transitions to the valley end 4011. In this embodiment, the support guide part 401 is an inclined support guide surface, so that the valley end 4011 is lower than the peak end 4012 and gradually transitions to the valley end 4011, which ensures that the support guide part 401 drives the trusted part 201 to rotate while the trusted part 201 rolls smoothly on the two support guide parts 401 under the driving force of the lifting device 300, thereby ensuring the smooth rotation of the upper die 200.

[0049] Further improvement is, further comprising a switching assembly 600, the switching assembly 600 is used for switching the relative height position of the two support guides 401, the switching assembly 600 is a rotating assembly, the rotating assembly drives the support guide 400 to rotate around the vertical direction and the rotation angle is 180° odd times.

[0050] Specifically, the switching assembly 600 is arranged at the output end of the lifting device 300, the switching assembly 600 is a stepping motor, the step angle is 180°, and the rotating shaft of the stepping motor is connected with the support guide 400. After the above structure is adopted, when it is needed to adjust the relative height position of the mold closing side support guide and the mold opening side support guide, the support guide 400 is only needed to be driven to rotate 180° by the stepping motor, so that the position of the higher support guide 401 and the position of the lower support guide 401 are exchanged, that is, the relative height position of the mold closing side support guide and the mold opening side support guide is changed. It should be noted that the rotating assembly can also adopt other mechanical structures, so that the support guide 400 rotates 180° odd times each time, that is, the relative height position of the mold closing side support guide and the mold opening side support guide can be adjusted. Furthermore, the output end of the switching assembly 600 can be connected with the lifting device 300, that is, the switching assembly 600 is connected with the support guide 400 through the lifting device 300, and the above technical effects can also be achieved.

[0051] After all the above structures of the mold base in the embodiment are adopted, the running schematic diagram is as shown in Figure 5 The seven states are switched and adjusted in sequence to form a closed loop operation to complete the repeated cycle operation of the mold opening and closing of the upper mold 200 and the lower mold 100, and the operation is labor-saving, stable and safe.

[0053] In the state (b), the lifting device 300 drives the support guide 400 to move upward, so that the support guide 401 on the mold closing side contacts the supporting part 201, drives the upper mold 200 to rotate upward, and the supporting part 201 rolls from the peak end 4012 of the support guide on the mold closing side to the valley end 4011 in the process that the center of gravity of the upper mold 200 approaches the reference plane, and the upper mold 200 keeps counterclockwise rotation;

[0054] (c) state, the lifting device 300 drives the support guide 400 to rise to the highest position, so that the upper die 200 center of gravity through the reference surface into the mold side, the support guide 400 from the valley end 4011 of the mold side to the valley end 4011 of the mold side, and the mold side of the support guide 401 contact, while the center of gravity of the upper die 200 also from the mold side through the reference surface to the mold side, the upper die 200 still keep counterclockwise rotation;

[0055] (d) state, the lifting device 300 drives the support guide 400 to drop to the same height position as (a) state, in the process of descending, the support guide 400 from the valley end 4011 of the mold side to the peak end 4012 of the mold side, and the mold side of the support guide 401 contact, while the center of gravity of the upper die 200 also from the mold side through the reference surface to the mold side, the upper die 200 still keep counterclockwise rotation, and finally the support guide 400 drops to the same height position as (a) state;

[0056] (e) state, the switching assembly 600, that is, the stepper motor drives the support guide 400 to rotate 180°, adjusts the relative height position of the two support guide 401, so that the mold side of the support guide is located on the side of the mold side of the support guide;

[0057] (f) state, the lifting device 300 drives the support guide 400 to rotate upward, so that the mold side of the support guide 401 contacts the support guide 201, and the upper die 200 is driven to the clockwise rotation, that is, the upper die 200 rotates clockwise, while the center of gravity of the upper die 200 approaches the reference surface, and the support guide 201 rolls from the peak end 4012 to the valley end 4011 along the mold side of the support guide 401;

[0058] (g) state, the lifting device 300 drives the support guide 400 to rise to the highest position, so that the center of gravity of the upper die 200 passes through the reference surface into the mold side, the support guide 400 from the valley end 4011 of the mold side to the valley end 4011 of the mold side, and the mold side of the support guide 401 contact, while the center of gravity of the upper die 200 also from the mold side through the reference surface to the mold side, the upper die 200 still keep counterclockwise rotation; after the lifting device 300 drives the support guide 400 to move downward, so that the upper die 200 rotates clockwise downward, the support guide 201 from the valley end 4011 of the mold side to the peak end 4012 of the mold side, and the upper die 200 rotates to the mold position shown in (a) state, the support guide 400 is separated from the support guide 201, and the upper die 200 is combined with the lower die 100, and then the corresponding operation is carried out according to (a)-(g) state.

[0067] After adopting the above structure, the height positions of the two unit plates 402 are changed by controlling the operation of the two switching oil cylinders 601, and then the relative height positions of the support guide parts of the mold closing side and the mold opening side can be adjusted, so as to realize the operating states shown in Figure 5 (a) to (g) and achieve the same technical effect.

[0068] Third embodiment

[0069] As shown in Figure 9 and Figure 10 , the production mold frame of the door and window composite profile of the third embodiment of the present application is based on the first embodiment, and the difference lies in that it further includes a transmission assembly 500, the transmission assembly 500 drives the mold to move along the horizontal direction perpendicular to the rotation axis of the upper die 200, the driving assembly includes two lifting devices 300 distributed along the transmission direction of the transmission assembly 500, and the support guides 400 corresponding to the two lifting devices 300 are symmetrically distributed.

[0070] Specifically, the transmission assembly 500 includes a transmission motor 501 fixed to the ground. A drive shaft 502 is coaxially connected to the output end of the transmission motor 501. Drive sprockets 503, evenly spaced along their axial direction, are fixedly connected to the outer circumferential edge of the drive shaft 502. The drive sprockets 503 are connected to driven sprockets 505 via a transmission chain 506. Driven sprockets 505 are coaxially connected to each other via driven shafts 504. Support bearings 120 are provided at both ends of the driven shaft 504 and at the end of the drive shaft 502 furthest from the transmission motor 501 to support the stable rotation of the drive shaft 502 and driven shaft 504. A base plate 130 parallel to the length of the drive shaft 502 is mounted on the transmission chain 506. The lower mold 100 is aligned with the length of the base plate 130 and mounted on it.

[0071] The transmission motor 501 rotates, which drives multiple drive sprockets 503 to rotate via the drive shaft 502. In conjunction with multiple driven sprockets 505 on the driven shaft 504, the transmission chain 506 rotates, which in turn drives the mold above to move via the base plate 130.

[0072] Lifting devices 300 are installed at adjacent points at both ends of the transmission chain 506. The output end of the lifting device 300 is connected to the support guide 400 through a buffer assembly 110. In the support guides 400 corresponding to the positions at both ends of the transmission chain 506, the two support guide parts 401 are distributed in opposite directions. Figure 10 As shown, at the left end, the left-side support guide 401 is positioned relatively low, which can be used for, for example... Figure 5 The operation proceeds from state (a) to state (c), and then the mold is transferred to the right end position via the conveyor chain 506. In the right end position, the left support guide 401 of the support guide 400 is positioned relatively higher, which can be used for operations such as... Figure 5 After operating from state (e) to state (g), the mold is then transferred to the left end position, and the mold can be used for cyclical operation of mold closing and mold opening without adjusting the position of the two support guides 401 on the mold closing side and the mold opening side.

[0073] Of course, in this embodiment, more than two molds can be placed on the transmission chain 506. When one of the molds is opened, that is... Figure 5 During operations (a) to (c), a mold closing operation is performed on the other mold, that is... Figure 5 The operations in (e) to (g) thus improve the production efficiency of composite profiles for doors and windows.

[0074] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
